Fluoride, water and cognitive health across the life course

Examining whether exposure to community water fluoridation across the life course relates to cognitive outcomes in childhood and later life, using two of Ireland's major longitudinal cohorts.

About the programme

Why fluoride, water and cognition

Community water fluoridation has been part of Ireland's public health infrastructure for decades, with a strong and consistent evidence base for its role in reducing dental decay. Far less is known about whether lifetime exposure to fluoridated water has any relationship with cognitive outcomes, in either direction, across childhood and into older age.

This programme uses two of Ireland's national longitudinal studies, Growing Up in Ireland and TILDA, to examine this question using population-representative data collected over many years, rather than a single cross-sectional snapshot.
